As I read some great comments by Dan Gillmor, Dave Winer and other bloggers about the shuttle tragedy, I was reminded about the story of one of the first Japanese submarines. Japan was doing research on submarines, but one of the first trials went terribly wrong. The submarine sank to the bottom of the ocean and the men began to die as oxygen was depleted. They recovered the diary of the captain of the ship. In the diary, the captain pleads to the government and the people of Japan to continue the research and not allow the failure of the mission to slow it down. The diary is quite moving. I bet that if the crew of the space shuttle had had the time to write, they probably would have written something similar.
